MINE-CAR.

Specificationof Letters Patent Patented Apr. 27, 1920.

Application filed December 16, 1919. Serial No. 345,329.

To all whom it may concern Be it known that I, KLAUs SoLLIE, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented a new and useful Improvement in Mine-Cars, of which the following is a full, clear, and exact description.

The present invention relates broadly to cars, and more particularly to that type known as mine cars.

The principal object of the present invention is to provide a car having an increased carrying capacity without any increase in the size of the car.

A further (@ject of the invention is to providea car of less height than that of cars ordinarily employed, but having an increased carrying capacity.

A still further object of the present in: vention is to provide a car having the main bottom portion thereof formed of wood, the remainder of the bottom and sides being formed of metal having wheel-receiving openings therein.

Still another object of the invention is to having transversely extending bracing members with enlarged ends constituting coverings for the wheel receiving openings formed in the metallic portion of the car body.

The foregoing and other objects, together with their attendant advantages, will be apparent as the invention becomesbetter unprovide a car derstood by reference to the accompanying specification and drawings forming a part thereof, it being premised that changes may be made in the various details and the man ner of operation within the scope of the appended claims without departing from the spirit ofthe invention.

Figure 1 is a top planview of a car constructed in accordance with the present invention. t

Fig. 2 is a longitudinal-sectlonal view of the car shown in Fig. 1, and

Fig. 3 is a transverse sectional view on the line III-III of Fig. 1. I

It is obvious that mine cars are limited so far as their outer dimensions are concerned, by the size of the entries through which the cars must pass. the cars is increased it will necessitate added labor on the part of the miners during the If the height of loading of the cars, and will leave less room between the upper edges of the car body and the roof of the mine entries. It is desirable that the sides of the cars be constructed-as low aspossible, but that the cars have a large carrying capacity. It is the object of the present invention to, provide for the construction of such a car.

Experiments have shown that mine cars constructed entirely of metal are notcapable of withstanding continued usage as the bottoms thereof buckle and break- Accordingto the present invention the cars are constructed with the main bottom portion thereof formed of wood and the remaining bottom portions and sides are formed of metal.

Referring more particularly to the drawings, there is illustrated a mine car having the usual wheeled trucks 2 carrying a wooden bottom 3. This bottom is prefer-.

iary metallic bottom portions 6 extending on opposite sides of the main wooden bottom of the car are provided with wheel-receiving openings 8 into which the wheels are adaptedto project. Cars as ordinarily constructed heretofore have had the metallic sides inclined upwardly away from the ,main bottom portion to provide sufficient room for thewheels. It is obvious that with a construction of this type the carrying capacity of the car is materially decreased. According to the present invention, there are preferably provided hollow metallic transverselyv extending bracing members 9 having enlarged end portions 10 forming pockets cooperating with the wheel openings 8 and forming coverings therefor.

' Due to the fact that each of these pockets 10 is only of sufiicient size to form a proper housing for the. wheels. the main interior portion of the car is unobstructed-so that the carrying capacity thereof is materially increased.

" preventing sagging Due to the provision of the transversely extending bracing members, the wooden \portion of the bottom and the metallic portions are materially strengthened, thereby of the "bottom. I also' preferably provi e triangularly shaped bracing plates 11 having flanges l2 permitting the sameto be readily secured' to'the metal car sides andto the upper portions of each of the pockets 10. In this manner the sides of the cars are prevented from bulglhe car is also preferably provided with channel-shaped or angle members 14 between the car bottom andthe bearing boxes serving asadditional ties for the floor and also tending to keep the boxes in place.

The advantages of my invention arise from a car construction in which the majority of the interior space of the car is rendered available for receiving the material being handled. v

A further advantage results from the provision of .the transversely extending 25 bracing members performing the double function of bracing the car bottom and covering the'wheel openings.

I claim: k 1. A car having metallic sides and metallic'bottom portions, said metallic bottom portions being provided with wheel receiv-.

ing openings, a wooden bottom cooperating with said metallic bottom portions, and bracing members extending transversely of the'bottom portion and overlying said openings, substantially as described,

2. A car havin metallic sides and metallic bottom portions, said metallic bottom portions being provided with wheel receiving openings, a wooden bottom cooperating with said metallic bottom portions, and bracing members extending transversely of the bottom portion and having enlarged end portions overlying the wheel openings and forming coverings therefor, substantially as described. I I

3. A car body provided with wheel receiving openings in'the bottom thereof, and

members having enlarged end portions forming housings for the wheel openings, substantially as described.

6. A car body provided with wheel-receiving openings in the bottom thereof,

bracing members extending transversely of the bottom and forming coverings for/said openings, and bracing plates cooperating with said members, substantially as described.

7. A metallic car body provided with wheel-receiving openings in the bottom thereof, a main wooden bottom portion intermediate said openings, and bracing mem bers extending transversely of the bottom and forming coverings for said openings,

substantially as described.

8. A- car body having wheel-receiving openings in the bottom thereof, and housing members cooperating with said openings,

the housing members on opposite sides of the car body being connected by transversely extending bracing members sub stantially as described. I 3

In testimony whereof I have hereunto set my hand.

KLAUS SOLLIE.
